Get words containing a specified sequence of letters (or word fragment) anywhere in the word. The Word Fragment can be any number of letters long and must occur in the same order that you specify anywhere in the matched words. The number of letters in the word must be greater or equal to the number of letters in the sequence for a match to occur. In computer programming terminology, this is known as a substring. It can be used to identify words that have a common word root / word base. You can also use it to identify semi-rhymes (word pairs that have an extra syllable on the end of one of the words e.g. mind blinding.)
